This paper outlines the up-to-date methods of internal pipeline corrosion control. The methods are based on controlling the amounts of water phase and gaseous phases that dissolve in water (including CO₂, O₂, and H₂S), as well as on cleaning, inhibition, and optimized design. The paper presents the feasibility of environmental control, which covers degasification and dehydration, pipe cleaning, which covers pigging and internal coating, and inhibitors. The paper discusses the influence of the operation conditions of consideration to a corrosion control method.
